Tyson Fury has revealed he waited until he got back to his hotel to drink water for fear of being drugged after the fight by "cheats" in Wladimir Klitschko's camp.
The 27-year-old upset the long-reigning Klitschko in Dusseldorf on Saturday night – picking up the WBA, WBO and IBF world heavyweight titles in the process.
Fury said on Monday: "I went home dehydrated before I even touched anything, I was so frightened of being drug-tested and failing the drugs test.
"They are cheats. They are extremely good at cheating."
The lead-up to the fight was littered with controversy, with many claiming Klitschko's team were guilty of tactics that were at best psychological warfare.
Early in fight week, Team Fury revealed they were yet to be issued with a pair of Paffen gloves (Klitschko's choice of handwear) that fitted the challenger.
At the beginning of fight night, Fury stepped on the ring in the Esprit Arena for the first time – only to discover that his foot sank deep in to the canvas. After much argument, organisers agreed to remove a thick layer of foam underlay (one of three layers).
Lastly, there was further uproar in the Fury camp just before the pair were due to ringwalk when Klitschko took the bizarre decision to wrap his hands without a representative from the opposite team present. Fury's father John threatened to call the fight off before Klitschko cut off his wraps and started again.
Several fighters have been quick to throw their hats in to the ring to challenge the newly-crowned champion – including former WBA champion David Haye, current WBC champion Deontay Wilder and the promising Anthony Joshua.
But Fury said: "I don't know what I'm going to do next. If I don't fight again, I'll know I've achieved what I set out to do. If I never won another fight I'd be happy. I said this is what I wanted to do from the beginning.
"All these people can do what they want. I'm not really interested in boxing at the moment. I've had a full six months of boxing. I've had a full six months of it. It's like winning the lottery and still buying lottery tickets – I'm not bothered.
"I'm heavyweight champion of the world and I'm trying to get used to that at the moment. Nothing about fighting, training. I'm not thinking about anything."
